Can I change the user/group of hdfs from clickhouse to others?

[JiangXiNJU]

hi，I'm trying to test cnch on hdfs. However, even if I change the owner of /root/app/usr/bin/clickhouse from clickhouse to others, the user on hdfs is still clickhouse.

Can I change the clickhouse's user on hdfs with some lightweight modifications? such as modify the xml ?

@JiangXiNJU Do you have the storage_configuration? You can set the hdfs path in xml file such as server_hdfs_disk0

<storage_configuration>
        <disks>
            <default></default>
            <server_local_disk1>
                <path>/xxx/server/data/</path>
            </server_local_disk1>
            <server_hdfs_disk0>
                <path>/user/clickhouse/</path>
                <type>bytehdfs</type>
            </server_hdfs_disk0>
        </disks>
        <policies>
            <default>
                <volumes>
                    <local>
                        <default>default</default>
                        <disk>default</disk>
                        <disk>server_local_disk1</disk>
                    </local>
                </volumes>
            </default>
            <cnch_default_hdfs>
                <volumes>
                    <hdfs>
                        <default>server_hdfs_disk0</default>
                        <disk>server_hdfs_disk0</disk>
                    </hdfs>
                </volumes>
            </cnch_default_hdfs>
        </policies>
    </storage_configuration>

Yes, I have already changed the path to /user/zhxxx/byconity/xxx
But the user is still clickhouse.
